Brush



FIG. 1 is a top view.

FIG. 2 is a bottom view.

FIG. 3 is a right side view of the decorative view with the left side view being a mirror image thereof; and,

FIG. 4 is an isometric view.

The portions of the front of the brush neither shown in the drawing nor described in the specification form no part of the claimed design. 

I claim the ornamental design for a brush, as shown and described.
